The invention relates to a device for tightening the strings of a keyboard musical instrument. The device provides for rigidly securing a tuning pin in position by means of a collet pressing into a cast-iron frame, an elastic ring being mounted on windings of a string. The present technical improvements increase tuning stability and tuning retention, increase string resistance to breaking, and increase the service life of a musical instrument.

Aspects of the disclosure provide for mechanisms for providing muting functions for a piano system. In some embodiments, a piano system according to the disclosure includes a plurality of linkage structures coupled to a plurality of keys, a plurality of strings corresponding to the plurality of linkage structures, and a muting unit configured to place at least one elastic structure at a first position to implement a first mode for the piano system. In some embodiments, the first position is located between the linkage structures and the strings. In the first mode, the elastic structure may be placed at the first position to prevent an interaction between at least one of the linkage structures and the strings when one of the plurality of keys is depressed.
